HAY-STACKER.

SPECIFICATION forming part or Letters Patent No. 716,738, dated December23, 1902.

Application filed May 7, 1902.

To aZZ whom it may concern.-

Be it known that I, MARVIN H. MOONEY, a citizen of the United States,residing at Gault, in the county of Grundy and State of Missouri, haveinvented certain'new and useful Improvements in Hay-Stackers, of whichthe following is a specification.

This invention relates to certain new and useful improvements inhay-stackers of that type in which the fork is carried by swinging armsmounted to move in the arc of a circle from a substantially horizontalto a substantially vertical position; and the purpose of the presentimprovement is to embody in a device of this class two stackersconnected for simultaneous operation, whereby when one is elevated anddelivering its load the other is lowered to receive a load or jag, thetwo stackers being so organized as to practically counterbalance andoperated by a horsepower from which extend cables or the like, the slackon one cable directly operating in connection with one stacker looseningthe remaining portion of the cable connecting with the other stacker.

A further object of the invention is to facilitate the formation of astack and elevate more hay or straw within a given time by;

the same amount of power than is usually required to operate one stackerand also to embody in each of the stackers, which are cooperativelyrelated, means for topping the stack.

With these and other objects and advantages in view the inventionconsists in the construction and arrangement of the several parts, whichwill be more fully hereinafter.

described and claimed.

In the drawings, Figure 1 is a perspective view of a stacker embodyingthe features ofthe invention and shown arranged in'operative position.Fig. 2 is a rear elevation of one of the stackers shown elevated and apart of the frame supporting the same. Fig. 3 is a detail plan view ofan attachment used in connection with each fork for locking the tines inposition for topping. Fig. 4 is a transverse vertical section throughthe supporting-frame for the stacker, showing one of the stackingdevices in edge elevation and positions of adjustment in dotted lines.Fig.

vertical section through a portion of the supporting-arms of one of thestackers, showing means for lengthening or shortening said arms. Fig. 7is a top plan view of the horsepower device particularly arranged foruse with the double stacker and showing a portion of the frame of thelatter. "Fig. 8 is a longit udinal vertical section through the centerof the horse-power, with a portion of one of the base -runners of thestacker frame shown in side elevation.

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The numerals 1 and 2 designate, respectivcly, elongated runners, whichform the base structure for the entire device and with the partsattached thereto are adapted to be dragged over the ground-surface tothe place or position where it is desired to erect or form a stack.Secured to the upper edges of the runners 1 and 2 are cross-strips 3,which hold the said runners in positive spaced relation and'in'uprightposition, the said strips being terminally extended beyond the outerside of the runner 1. The strips 3 for a greater portion of their lengthare formed with longitudinal slots 4, which extend through the endsthereof connected to the upper edge of the runner 2, and pivotallysecured in the said ends of the strips resting on the runner 2 arecompensating bars 5, one being located in each strip and steadied intheir rising and lowering movements by brace-rods 6, attached theretoand movably connected to the upper edge of the runner 2 on oppositesides of the point of attachment ofthe strip 3. As both stacking devicesare similar in construction, one only will be particularly described. Onopposite sides of the strip '3 the lower ends of members 7 of thefork-arms are pivotally connected to therunner 1, and cooperatingtherewith are upper members 8, the respective members 7 and 8 beingterminally provided with angular sleeves 9, slidin'gly engaging saidmembers and held in adjustable position in relation to the latter bypins or bolts 10, whereby the arms are made telescopically adjustable toaccommodate different heights of the stack during the formation of thelatter. It will be understood that the engaged extremitiesof the members7 and 8 will be supplied with a suit length of said cables which may befound necessary in the operation of the stacker. It is obvious thatthese stop-cables 11 prevent the fork-arms from swinging over too far,but permit the fork to assume such angle that it will readily becomeunloaded or allow the charge or jag of hay or straw carried thereby toslip over onto the top of the stack. The upper members 8 are connectedto the head of an elevating fork or rake 14, comprising a plurality oftines 15, arranged in parallel planes with the said members 8 and havinga corresponding series of angular tines 16 pivotally connected thereto.For ordinary stacking purposes the tines 16 are permitted to occupy theangle shown by Fig. 1; but when it is desired to top the stack the saidtines 16 are elevated, as indicated by dotted lines in Fig. 4, and heldin such position by a keeper 17, comprising a bar 18, pivotally mountedat its ends to one of the fork or rake bars and adapted to be thrownupwardly under the tines 16. Between the lower extremities of themembers 8 and the head of the fork or rake 14E braces 19 are located andconnected at opposite terminals, respectively, to the fork or rake headand the lower terminals of the members 8. The braces 19 relieve thefork-arms of strain, particularly when the said arms are elevatedorduring the elevating operation thereof, and connected to the free endof the compensating bar 5 are the two ends ofpull-rods or analogousdevices 20, which diverge and are attached at their opposite ends to thefork or rake head, the said pull-rods or analogous devices removing thepulling strain direct from the arms of the fork and transferring it tothe said fork. These pull-rods oranalogous devices 20 areintermediatelyseparable to accommodate lengthening and shortening of thearms, and when the members 8 of the arms are projected their full extentthe upper portions of the pull-rods are used. Then the arms aretelescoped, the upper portions of the pull devices are detached from thelower portions of said devices and folded into the heads of the forks,as shown by Fig. 2, and held against movement by the said lower portionsof the pulldevices, which then have their upper ends connected to theheads of the forks.

With the improved double stacking organization a particular form ofhorsepower is used, and comprises opposite runners 22, connected by across-strip 23, to the center of which a sweep 24 is pivotally attachedon the upper squared end 25 of a center post 26, rotatably mounted andvertically disposed in the said strip 23, the center post having itslower extremity depending below the strip and also squared, as at 27, toreceive a cableattach'ing arm 28,'provided with a loop swivel or eye 29in its outer end for this purpose. Through the medium of the center post26, constructed as set forth, the sweep 24 and arm 28 are caused to movesimultaneously and equally in proportion to their length, and at asuitable elevation in the runners 22 are a pair of guide-sheaves 30,disposed in a horizontal plane and in longitudinal alinement. The sweep24 is also supplied with suitable draft-attaching appliances, such as asingletree, and is long enough to permit a horse attached thereto totravel around the runners 22. The terminals of an operatingcable 31 orthe like are secured to'the eye 29 on the arm 28, and the oppositeportions of said cable are passed over the exterior portions of thesheaves 30, the one part of the cable extending away from the inner sideof one runner 22 and the other part from the outer side of the oppositerunner. That part of the cable which extends away from the inner side ofone runner passes over a sheave 32, horizontally disposed in the frontextremity of the runner 2 of the stacker organization, directly underthe secured end of the forward strip 3, and thence transversely acrossand through an opening 33 in the forward extremity of the runner 1, overa verticallydisposed sheave or pulley 34 in the end of the strip 3,which projects outwardly over said runner 1, and thence to the free endof the adjacent compensating-bar 5. The other part of the cable 31passes through a sheave or pulley 35, secured at an intermediate pointon the outer side of the runner 1, thence through a pulley or sheave 36on the end of the other cross-strip 3, and is terminally connected tothe adjacent compensating bar 5. It will be seen that the cable 31through the connection thereof to the arm 28 virtually becomes acontinuous cable terminally attached to the two compensating bars.

The purpose of connecting the cable-terminals to the bars 5 is torelieve the pulling strain directly from the arms of the forks or rakes,so as to prevent fracturing or breaking said arms, and the liability toinjury of the arms is further prevented by the use of the pull-rods oranalogous devices 20, heretofore explained and also attached to thecompensating bars.

The horse-power devices, as well as the compound sta'cking structuredisclosed, may be simultaneously 'moved from one place to another bydragging the same over the groundsurface through the medium ofconnectingrods 37, detachably secured to the front ends of the runners land 2 and the rear ends of the runners 22, as clearly shown by Fig. 7;but after the apparatus as an entirety has been disposed in the positiondesired the said connecting-rods may be detached and the horse-powermoved any distance desired from the stacking organization itself.

When the improved device as an entirety is arranged for use, the partswill be disposed as shown by Fig. 1, one set of armsand their forksbeing lowered and the other elevated and the horse-power placed at adistance from the front extremities of the runners 1 and 2. To permitthe arms of each fork or rake to lower very close to the ground-surface,the upper edge of the runner 2 at the front and rear extremities isformed with slots 38, into which the arms of the forks or rakes areadapted to be depressed, as clearly shown by Fig. 1. The improved devicehaving been arranged in convenient position to the quantity of straw orhay to be stacked, the arm 2' is set in rotative motion by means ofadraftanimal, the one fork being first loaded with the hay or straw byan operator, it being understood that the fork or rake which is loadedwill be the one that is in lowered position. When the sweep 24; is movedfrom the position shown by Fig. l in the direction of the arrow, theright-hand portion of the cable 31 will be drawn forwardly by the arm28, and thereby gradually elevate the forward fork or rake by pullingonthe compensating bar 5, which when the said fork or rake is loweredwillstand in an approximately vertical position. The pulling force ofthe said righthand portion of the cable will be exerted through thecompensating bar and the pullrods or analogous devices 20andconcentrated on the head of the fork or rake, and as the said forwardfork or rake is elevated the left-hand portion of the cable is graduallyslackened or moved rearwardly and allows the rear fork or rake to lower,and when said rear fork or rake is at its lowest position it is loadedand immediately starts to elevate just at the time that the forward forkor rake is unloaded or has deposited its load on the stack. Thiselevating operation of the rear fork will occur when the sweep 24arrives at a point approximately opposite that shown by Fig. '1, andsimultaneously the forward fork will begin to lower, and thus thealternate elevating operation of the two fork structures is carried onregularly withoutreversing the draft-animal and during the continuousmovement of said animal in one direction. This is due to the fact thatwhen the arm 28 terminally arrives in its closest relation to the twosheaves or pulleys 30 of one runner 22 all the slack necessary in theone portion of the cable to permit the fork or rake structure controlledthereby to fully lower will have been exhausted and the pulling strainon the other portion of the cable necessary to elevate the remainingfork structure will have been completed, and immediately the forkstructure that has been lowered will start to rise or elevate and theone that was elevated will lower. By this means a stack may be quicklyformed, and in view of the fact that the two fork structurescounterbalance each other or are exact counterparts in weight thedraft-animal is only required to lift approximately the same loadweight, and, in fact, the load weight will be slightly decreased in viewof the assistance in pulling the cable, due to the lowering of the emptyfork structure.

The improved device is comparatively simple in its construction, and inview of the economicaloperation and expedition resulting in theformation of a stack owing to the dual fork organization a very usefulfarming implement will be produced.

Having thus fully described the invention, what is claimed as new is 1.A hay-stacker having dual fork structures adapted to be alternatelyraised and lowered by pulling power applied from a single source.

2. A hay-stacker having dual fork structures and power appliancesadapted to alternately elevate and depress the same.

3. A hay-stacker having dual fork structures of equal weight adapted toalternately elevate and depress, and a cable device connected to thesaid structures and actuated from a single power-producing medium.

4. A hay-stacker having fork structures adapted to alternately elevateand depress, the elevation of one structure assistingin the depressionof the other and vice versa.

5. A hay-stacker comprising a pair of independent fork organizations,and operating devices correlatively connecting said organizationswhereby when one is elevated the other will be depressed, and viceversa.

6. A hay-stacker comprising a pair of independent fork organizationsmovably mounted to alternately elevate and depress, a horsepower havingan arm, and anoperating pull device made continuous through attachmentto said arm and terminally connected to said fork organizations.

In testimony whereof I affix my signature in presence of two witnesses.
